Abstract
Abstract A storage system comprising dual compartments in which materials requiring temperature and humidity control are stored. The double compartments with different locks include a system of inventory control as well as stock rotation. The compartment which is filled first is used first and, when empty, an order for replacement stock is made. Both compartments are controlled to stabilize temperature and humidity by a single control unit which is a separable unit.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
237 words
An air conditioned storage system comprising: two storage compartments each with a separate closure means, said compartments separated by an air permeable but article retaining wall; said compartments connected to a container for housing the compartments of a refrigeration system and including a first air duct in the container for housing hot portions of the refrigeration means, a first fan for forcing air through the first duct to cool the hot portions, a second air duct in the container for housing cold portions of the refrigeration means together with parts of the hot portions, a second fan for forcing air through the second duct to lower the air temperature; said hot portions of the refrigeration means including a motorcompressor for compressing a refrigerant fluid, and a series of hot pipes for receiving the compressed fluid; the cold portions of the refrigeration means including a series of cold pipes and an expansion valve connected between the hot pipes and the cold pipes; a first thermostat in the second duct for controlling the action of the motor-compressor; a movable baffle forming a part of a wall between the first and second air ducts and having holes therein for enclosing lengths of said hot pipes; and a second thermostaT in an exit portion of the second duct for varying the position of the baffle to expose variable lengths of the hot pipes to the air passing through the second duct.

Claim 3
Dependent Claim
27 words
A system as claimed in claim 1 wherein said baffle is connected to the wall between the first and second ducts by an accordion pleated flexible diaphragm.
Claim 4
Dependent Claim
28 words
A system as claimed in claim 1 wherein a water saturated fiber mat is positioned in the second duct to increase the humidity of the air passing therethrough.
Claim 5
Dependent Claim
44 words
A system as claimed in claim 1 wherein a storage tank containing water is positioned at the bottom of the second air duct and a pump conveys water from the tank to an evaporation means for stabilizing the humidity of the air passing therethrough.
Claim 6
Dependent Claim
21 words
A system as claimed in claim 4 wherein the evaporation means is a fibrous mat positioned in the second air duct.
Claim 7
Dependent Claim
22 words
A system as claimed in claim 4 wherein the evaporation means is a plurality of jets for producing a finely divided mist.
Claim 8
Dependent Claim
30 words
A system as claimed in claim 6 wherein said jets are directed toward a plurality of cold pipes for maintaining the temperature of the jet water within a desired range.
Claim 9
Dependent Claim
36 words
A system as claimed in claim 6 wherein the water from the pump is directed through a heat exchanger to reduce the water temperature to a predetermined value before being sprayed into the second air duct.
Claim 10
Dependent Claim
24 words
A system as claimed in claim 8 wherein the heat exchanger is cooled by the cold refrigerant fluid after it leaves the cold pipes.
Claim 11
Dependent Claim
35 words
A system as claimed in claim 8 wherein a plurality of louver slats are positioned above said jets in the second air duct to prevent water drops from being ejected from the second air duct.
